"The easiest way to install KDE on Windows is to download the
installer and run it from your Windows desktop. Windows 2000, XP,
and Vista are all supported. The installer is possibly complicated
enough that it will make the average Windows user uneasy, but,
since it results in a non-destructive installation that’s
easy to remove, nobody should be intimidated by it.
"Mostly all you need to do is follow the instructions slowly and
carefully, accepting the defaults wherever you don't understand. In
this way, you can quickly move through the first part of the
installer, choosing to install from the Internet, using C:Program
Files as the installation directory, and choosing Enduser as the
install mode.
"Then you can navigate the mysteries of selecting a mirror by
choosing the download site nearest to you, and choosing the latest
stable version of KDE on Windows to install. At that point, you
just need to select everything to install, and choose any
additional language support you want besides the default American
English. After that, installation is a matter of watching a
progress bar for fifteen minutes."
